Motor starting torque
NettetThe starting torque is very low due to voltage reduction; The resistors are quite expensive for large motors. Rotor Resistance or Slip Ring Motor Starter. This type of motor starter works on a full voltage motor … Nettethigh as 180 – 220% of the motors full load torque (FLT). Using the VFD’s constant Volts/Hz relationship, the VFD can be operated to provide motor starting torque equal to approximately 80% of the motor’s BDT. The combination of a VFD and motor can provide great advantage for starting a high inertia fan load, or to generate the high ...
